We note here that in contrast to the dual source fig:ds-foraging model studied
by [1]}, the power law target distribution studied here is not nearly
as conducive to self-organization, which results in the lower scalability values
across all algorithms seen here. In addition, constant density swarms further lower the
self-organization potential of the environment, resulting in lower scalability and
self-organization values than the first scenario. Our findings on this and the
previous scenario are in rough agreement with the positive correlation hypothesis
between self-organization and performance/scalability from [1]}:
algorithms with higher levels of self-organization perform better and are more
scalable. However, our results in the two studied scenarios suggest that raw
comparison of self-organization curves is not sufficient, because different
algorithms require different levels of self-organization to achieve the same
performance.
